Guanghao Zhang updated HBASE-16868:
-----------------------------------
Release Note: Add a replicate_all flag to replication peer config. The default value is
true, which means all user tables (REPLICATION_SCOPE != 0 ) will be replicated to peer cluster.
If you only need replicate some namespaces or tables, you need set replicate_all flag to
false first. Then add special namespaces or table-cfs config to the replication peer.
> Add a replicate_all flag to avoid misuse the namespaces and table-cfs config of replication
peer

> Key: HBASE-16868

> Project: HBase
> Issue Type: New Feature
> Components: Replication
> Affects Versions: 2.0.0, 3.0.0
> Reporter: Guanghao Zhang
> Assignee: Guanghao Zhang

>
> First add a new peer by shell cmd.
> {code}
> add_peer '1', CLUSTER_KEY => "server1.cie.com:2181:/hbase".
> {code}
> If we don't set namespaces and table cfs in peer config. It means replicate all tables
to the peer cluster.
> Then append a table to the peer config.
> {code}
> append_peer_tableCFs '1', {"table1" => []}
> {code}
> Then this peer will only replicate table1 to the peer cluster. It changes to replicate
only one table from replicate all tables in the cluster. It is very easy to misuse in production
cluster. So we should avoid appending table to a peer which replicates all table.
